A bracket assembly including a front bracket and a rear bracket supports a a side rail assembly configured to support a drawer for movement between an extended position away from the bracket assembly and a retracted position toward the bracket assembly. A hook is configured to releasably join the bar assembly to the bracket assembly.

FIELD OF THE INVENTION

This invention relates to storage cabinets, and particularly a kit for amodular pull-out drawer for easy installation into a storage cabinet.

BACKGROUND OF THE INVENTION

Kitchen pantries and other similar cabinets are often configured withinterior shelves that do not pull out. Consumers commonly retrofit suchcabinets with drawers that can be extended out of the cabinet for easieraccess to the stored items that may be in the back of the cabinet. Thehousewares market contains many examples of such pull-out cabinet drawerdesigns. Such designs may include a drawer or tray that is affixed totracks that are screwed into cabinets so the drawer (or tray) slides inand out of the cabinet.

One problem is that consumers must screw the tracks into the wood of thecabinet to install them, so that they are firmly mounted to the cabinet.Not only is this a hassle to install, requiring time, tools and somedegree of do-it-yourself (DIY) experience, but it puts permanent holesinto the expensive wood cabinets. This may be especially challenging ifthe cabinet is made from solid surface materials which may be difficultto screw into, or if the wood is too soft to firmly retain a screw. Forthese reasons, many people are reluctant to install such modular drawerswith screws. If the consumer is renting the home or apartment, there isalso the risk of losing security deposit money for damaging the cabinetif the drawers are removed because the screw holes will remain.

SUMMARY OF THE INVENTION

In accordance with a preferred example of the invention, a drawerassembly is modular to enable an existing cabinet to be retrofitted(though it may be used in new construction), and therefore the preferredexample is in the form of a kit for mounting a modular drawer within acabinet having a horizontal planar floor and a pair of opposing cabinetsidewalls extending vertically upward with respect to the floor (whichmay be a shelf).

The kit preferably includes a bar assembly having a first end and anopposing second end with an adjustable length between the first end andthe second end, the adjustable length being selectively configurable toallow the bar assembly to span the pair of opposing sidewalls; a bracketassembly including a front bracket and a rear bracket; a drawer; a siderail assembly supported by the bracket assembly, the side rail assemblybeing configured to support the drawer for movement between an extendedposition away from the bracket assembly and a retracted position towardthe bracket assembly; and a hook configured to releasably join the barassembly to the bracket assembly, wherein the bar assembly retains thebracket assembly within the cabinet when the bar assembly is mountedwithin the cabinet and spans the pair of opposing sidewalls.

In one version, the kit may include a first side mount and a second sidemount, each of the first side mount and the second side mount having afirst face with adhesive for attachment to one of the cabinet sidewallsand an opposing second face with a mounting structure; a telescopingtube assembly having a first end terminating in a first end cap and anopposing second end terminating in a second end cap with an adjustablelength between the first end and the second end, the adjustable lengthbeing selectively configurable to allow the bar assembly to span thepair of opposing sidewalls, each of the first end cap and the second endcap being attachable to a separate one of the mounting structures; abracket assembly including a front bracket and a rear bracket; a drawer;a side rail assembly attached to the bracket assembly, the side railassembly being configured to support the drawer for movement between anextended position away from the bracket assembly and a retractedposition toward the bracket assembly; and a hook configured toreleasably attach the tube assembly to the bracket assembly, wherein thetube assembly retains the bracket assembly within the cabinet when thetube assembly is mounted within the cabinet and spans the pair ofopposing sidewalls.

In one version, the tube assembly comprises a small tube telescopicallyreceived within a large tube.

In some versions, the small tube further comprises a spring-loadedbutton carried on the small tube, and the large tube comprises aplurality of holes extending along a length of the large tube, whereinthe button may be selectively extended through a chosen one of theplurality of holes to adjust the length of the bar assembly.

In some versions, the tube assembly defines an axis between the firstend and the second end of the tube assembly, and the second end capcomprises a spring cap, the spring cap having a spring housing a springtrapped within the spring housing, wherein the spring cap is moveable ina direction along the axis to decrease the length of the bar assemblywhen the spring is compressed.

In some examples of the invention, the kit includes a first footattached to the rear bracket, the hook being formed as a portion of thefirst foot, the hook further extending vertically from the first foot toa first height when the bracket assembly is positioned on the floor.

In some examples, each of mounting structures are positioned on thefirst side mount and the second side mount to form a gap between thefloor and the tube assembly when the first side mount and the secondside mount are attached to the opposing vertical sidewalls, the gaphaving an upper end at a second height above the floor, wherein thefirst height is greater than the second height, thereby allowing thefoot to be slid beneath the tube assembly when the bracket assembly ispivoted about the hook, but preventing the bracket assembly from beingpulled out of the cabinet along a path defined by a plane parallel tothe floor.

In some versions, the first foot further comprises a planar portionattached to the rear bracket, and wherein the hook extends in adirection away from the front bracket and the rear bracket.

In some versions of the invention, the first side mount and the secondside mount are attached to the cabinet sidewalls, the tube assembly ismounted to and spans the first side mount and the second side mount, andthe bracket assembly is supported by the floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

An exemplary modular cabinet drawer is illustrated in FIG. 1, shown in aretracted position in which the drawer would be fully inside a cabinet(which is not shown in FIG. 1 but which is represented in otherfigures). In the illustrated example, the drawer includes an upperdrawer 200 formed as a wire basket, although in other versions thedrawer may be formed from wood or other materials, and may have a solidsurface rather than the number of openings between the spaced apartwires. Likewise, the drawer may have only a floor and need not havesurrounding vertical sidewalls, as in the illustrated example.

The drawer or tray is carried on at least one rail assembly such as theleft and right side rail assemblies 300, 301. In the preferred examples,the side rails are configured to extend and retract in a telescopingfashion.

In FIG. 2, the tray is shown in a partially extended position, and inthis position the telescoping nature of the preferred implementation ofa rail assembly is shown. Thus, in this version the rail assemblyincludes a pair of left and right rail assemblies 300, 301, in which theleft rail assembly 300 has a fixed side rail bracket 311 and a pair ofattached side rails 312, 313 that are mounted to be extended out of orretracted into the side rail bracket. Likewise, the right rail assembly301 has a fixed side rail bracket 321 and a pair of attached side rails322, 323 mounted in the same way.

The rail is supported at a front by a front bracket 400, and at the rearby a rear bracket 500. A bar assembly 600 is configured to be mountedbetween opposing sidewalls of a cabinet, and as discussed below ispreferably arranged to accommodate cabinets of a variety of widths. Inthe preferred example, the bar is configured as a tube having atelescoping arrangement.

In FIG. 3, the tray is shown in a fully extended position, exposing therear bracket assembly 500 and the bar assembly 600.

FIG. 4 shows a top plan view of the cabinet drawer, with the trayremoved for clarity of illustration of the remaining components. It isalso shown mounted within a cabinet 700 having a horizontal surface 701(such as a cabinet floor, or a shelf within the cabinet), sidewalls 702,703, and a back wall 704. Though shown installed in FIG. 4, it should beappreciated that the cabinet drawer is primarily intended to be made asa retrofit or modular kit, and therefore the installed version of FIG. 4is a configuration that occurs after the cabinet drawer has been mountedwithin a cabinet.

As illustrated, the bar assembly 600 spans the width of the cabinetbetween the opposing sidewalls 702, 703. A first side mount 610 isattached to a first sidewall 702, and a second side mount 611 isattached to a second sidewall 703. The bar assembly, which in thepreferred embodiment includes a telescoping tube as discussed below, ismounted to each of the first and second side mounts. Most preferably,the side mounts include an adhesive provided on the side mounts (whichis covered by a removable non-stick adhesive backing for shipment priorto use), such that the side mounts are affixed to the sidewalls by theadhesive. As further discussed below, the telescoping tube isspring-loaded to provide a force to hold the tube in place.

The modularity of the cabinet drawer allows it to be positioned withinthe cabinet as desired. Thus, the bar assembly 600 can be positioned ata desired distance D1 from the rear cabinet wall 704, to ensure that thecabinet drawer is positioned within the cabinet as close to, or as farfrom, the cabinet opening 705 as desired. Likewise, the cabinet drawerbracket structure (including the front bracket 400, rear bracket 500,and side bracket assemblies 300, 301) can be positioned centrallybetween the two sidewalls 702, 703, or can be skewed closer to eithersidewall as desired. In the example as illustrated in FIG. 4, thebracket structure (and therefore the cabinet drawer) is positionedcloser to a left sidewall 702 than it is to a right sidewall 703, sothat a first width W1 between the bracket assembly and the left sidewallis less than a second width W2 between the bracket assembly and theright sidewall.

The front bracket 400 may optionally include one or more holes or slots401, 402 to enable it to be mounted to a cabinet floor or shelf, such aswith screws. Most preferably, however, the front bracket is intended tobe placed on the cabinet floor or shelf without the use of anyfasteners. Likewise, the rear bracket 500 may include one or more holesallowing it to be bolted or screwed to a cabinet floor, though in thepreferred version it is intended to be mountable without such screws orbolts.

FIGS. 5-12 illustrate the bar assembly in greater detail, and separatefrom the rest of the cabinet drawer. The full bar assembly isillustrated in FIG. 5. As shown, it is attached to a pair of side mounts610, 611 to be mounted to a vertical cabinet side wall. The preferredbar in the bar assembly is configured as a telescoping tube comprised ofa first small tube 620 telescopically received within a second largertube 630. The large tube is configured with a plurality of holes 640,positioned and configured lengthwise along the tube to enable a selectorbutton 650 extending from the small tube to extend through a selectedone of the holes 640 to thereby control the length L1 of the combinedlarge and small tubes together. Thus, by repositioning the selectorbutton in a desired hole 640, the length L1 can be increased ordecreased. Accordingly, the cabinet drawer can be firmly mounted in acabinet of a variety of widths by adjusting the length L1 of the tube.

In alternate versions, the bar assembly may be configured differently,but preferably in a manner that allows it to be adjustably lengthened orshortened. Thus, the bar assembly may have internal threads or use otherfeatures to allow the length to be adjusted.

As seen in FIG. 6, the bar assembly terminates on a first side with afirst end cap 660 attached to the end of the small tube in the preferredembodiment. In the illustrated example, the end cap has a circularperimeter and forms a planar surface perpendicular to a long axisextending along the length of the bar (or tube assembly). At theopposite side, the bar assembly terminates in a second end cap which ispreferably a spring cap 670, and which also has a circular perimeter.The spring cap is configured to allow for resilient adjustment of theend cap, and to provide a spring-loaded force of the bar assembly withinthe pair of side mounts.

The spring cap is shown in an exploded view in FIG. 7, and in thepreferred embodiment as illustrated it includes a spring housing 680which receives and retains a coil spring 672. The coil spring is trappedbetween one end of the spring housing 680 and an interior surface of anend cap 674. The end cap 674 is either integrally formed with, or may beattached to an outer large tube sleeve 673. Thus, in the illustratedexample the end cap has a plurality of feet 676 which extend throughholes 675 in the large tube sleeve to attach the two componentstogether. When assembled, the large tube sleeve surrounds the springhousing and may be attached to the spring housing using an adhesive,sonic welding, friction fit, snap fit, or other means.

As shown in FIGS. 8 and 9, the spring housing 680 includes an interiorbarrel 681 sized and configured to receive the spring. An opening 682 ona first side of the spring housing allows for the insertion or removalof the spring. Preferably the spring is sized so that a portion of thespring (when in its relaxed state) extends fully into the barrel andrests against the end wall of the barrel while a portion of the springextends outward and beyond the opening so that it can engage the end capas discussed above.

As seen in FIG. 10, the button 650 is mounted on a V-spring 651 having afirst upright 652 and a second upright 653. The V-spring is insertedinto the small tube 620 so that the button 640 extends through the hole621 formed in the small tube (see FIG. 11), with the uprights of theV-spring compressed toward one another to urge the button through thehole in the small tube and to engage the interior sidewalls of the tubeto retain the V-spring within the tube.

A preferred side mount is shown in FIGS. 12 and 13, and in a preferredversion the side mounts may be formed to be identical to one another andinterchangeable; in other preferred versions they are a mirror image ofone another. Thus, in FIGS. 12 and 13 only a single side mount 610 isshown for simplicity. In yet other versions a first side mount may besomewhat different from the opposing second side mount, such as bychanging the size or positioning of a mounting feature.

FIG. 12 illustrates a first side or face 615 of the preferred sidemount, and in the illustrated example the first face is planar andcovered with an adhesive. During manufacture, a paper backing 618 maycover the adhesive (as illustrated, the adhesive is covered by the paperbacking 618 and not visible) provided on the first face, in order toprotect it until ready for installation. At the time of installation,the paper backing is removed so that the side mount 610 may beadhesively attached to the cabinet sidewall as shown and describedabove.

The opposing face 616 of the side mount 610 is shown in FIG. 13. In theillustrated example, the second face (that is, the opposing side) isalso planar and includes a mounting structure or feature 617 that issized and configured to receive a mating portion of the bar assembly.Most preferably, the mounting feature is an annular rib which extendsoutward from the second face of the side mount, sized and shaped toreceive the circular spring cap or end cap. Thus, as seen for example inFIG. 5, the small tube and small end cap is received within a firstannular raised surface of a side mount, while the spring cap is receivedwithin a second annular raised surface of a second side mount.

In order to form a bar assembly (or tube assembly) of the appropriatelength for a particular cabinet, a user depresses the button 650extending through a hole 640 in the large tube, then telescopicallyextends or contracts the assembly to increase or decrease its axiallength as desired. The button then extends through a different selectedone of the holes to lock the bar assembly in position. Most preferably,the bar assembly will then have a length that is greater than the lengthbetween the opposing cabinet sidewalls, so that the bar assembly must becompressed to actually fit within the side mounts. In order to insertthe bar assembly, the spring 672 within the spring cap must thereforecompress somewhat in order to fully accommodate the bar assembly. Thiscompression provides an additional force, helping to ensure that the barassembly is firmly mounted within the cabinet. To best achieve a snugand firm fit regardless of cabinet size, the spring and spring cap arepreferably configured so that the distance through which the spring capcan compress is approximately the same as (or somewhat greater than) thedistance between adjacent holes 640 formed in the large tube.

FIG. 14 is a bottom plan view which illustrates a bar assembly 600interacting with a rear bracket assembly 500, so that the bar assemblyretains the rear bracket assembly and therefore the cabinet drawer. Inthe illustrated example, as seen in FIGS. 14-16, the rear bracketassembly includes a horizontal rear bracket 510 having one or more feet520, 530, and an opposing pair of vertical side braces 511, 512. Asdescribed above and seen in FIGS. 1-3, the rear vertical side braces andcomplementary front vertical side braces 411, 412 support the side railassemblies. In the preferred example, two such feet are shown, each ofwhich is configured to rest on a cabinet floor or shelf to support thecabinet drawer within the cabinet.

The rear bracket assembly is shown in a side elevational view in FIG.15, in which one of the feet 530 is visible, and further in a topperspective view of FIG. 16. As shown, the foot preferably includes aplanar portion 540 resting below the rear bracket 510, and a hookportion 550 extending outward from the planar portion. Most preferably,the hook portion extends beyond the rear bracket 510, as shown, and iscurved upward, away from a plane A-A representing a cabinet floor orshelf, parallel to the planar portion 540 of the foot 530, and extendingtoward the rear bracket 510.

When mounted within a cabinet, the side mounts (e.g., 610) are placedwithin the cabinet so that a lower end 619 is resting atop the cabinet(or shelf) floor, which is represented by plane A-A in FIGS. 12 and 13and also in FIG. 15. FIG. 17 also illustrates the cabinet drawer mountedwithin a cabinet, and in this instance it is seen from the rearelevational view. The annular mounting ring 617 is positioned close tothe cabinet floor, as best seen in FIG. 13. The diameter of the smalltube end cap 660, and the diameter of the spring cap 670 are each largerthan that of the small tube 620 and large tube 630. Accordingly, acombination of the position of the annular mounting ring and therelative sizes of the tubes and end caps serves to create a small gap(indicated by arrow 710 in FIGS. 17 and 18) between the cabinet floor orshelf 701 (which also corresponds to the plane A-A above) and the barassembly or tubes, e.g., 620, 630. The gap is preferably sized to belarge enough to allow the hook ends 550 of the feet 540 formed on therear bracket to slide under the bar assembly, but only when the frontend of the bracket assembly is pivoted upward.

In accordance with a preferred version of the invention, the curved end550 of the feet 540 extends upward to a height H1 above the planarportion 540 to a height H1 as indicated in FIG. 15. The height H1 isdesigned to be greater than the distance of the gap between the cabinetfloor 701 and the lower end of the bar assembly, or more particularlythe lower end of the large tube 630. As illustrated in the close-updetail of FIG. 18, corresponding to detail 18 indicated in FIG. 17, thegap 710 is defined by a height H2 as described above, in which H2extends from the top surface of the cabinet floor or shelf 701 and thelower surface of the bar assembly, such as the large tube 630. Thus, inthe preferred version the height H2 is less than the height H1 so thatthe hook will abut and be impeded by the bar assembly when the shelf orbasket 200 is pulled outward from the cabinet in a direction thatfollows a plane parallel to the cabinet floor. In order to insert orremove the entire assembly, the assembly must be pivoted to allow thehooks to be positioned past the bar assembly. In some versions of theinvention, the feet or bracket assemblies (or both) may have resilientmaterials, such as non-skid supports 501, 502, 503, 504 illustrated inFIG. 19, attached to them on lower surfaces, to further aid in providingfrictional resistance against the bracket assemblies from sliding out ofthe cabinet.

The preferred version of the invention as illustrated and describedincludes a bar assembly that spans a pair of opposing cabinet sidewalls,with a hook positioned on a cabinet drawer bracket assembly so that thehook can engage the bar assembly. It should be appreciated that the hookcould be configured differently, for example to engage the upper surfaceof the bar assembly rather than the lower surface of the bar assembly.In one such version, for example, the feet 530 may be inverted andmounted atop the rear bracket 510 rather than beneath it.

In yet other versions of the invention, the hook is carried on the barassembly and engages a surface on the bracket assembly, such as the rearbracket 500. Such implementations may be, for example, a reversedimplementation of the versions described above, so that the feet (orother hook) are attached to the bar assembly and then engage the bracketassembly, rather than the other way around.

While the preferred embodiment of the invention has been illustrated anddescribed, as noted above, many changes can be made without departingfrom the spirit and scope of the invention. Accordingly, the scope ofthe invention is not limited by the disclosure of the preferredembodiment. Instead, the invention should be determined entirely byreference to the claims that follow.
